Of all the species of eel, levi elvers are said to most closely resemble Leviathan, although their much-reduced size does make them rather less imposing.
These large eels are held sacred by the Sahagin, who believe them to be the children of Leviathan. The same eels are quietly eaten by Rothlyt Sound sailors, who believe them to be delicious (and auspicious for safe voyages).
